Quiero visitar un pueblo del noroeste el próximo otoño.

In Spanish, subject pronouns are often omitted because the verb ending already shows who the subject is.

• quiero = I want
• The -o ending tells you it is yo

So Quiero visitar... is the most natural choice. You can say Yo quiero visitar..., but that usually adds emphasis, such as:

• Yo quiero visitar un pueblo, no una ciudad.
  I want to visit a village, not a city.

Because after querer (to want), Spanish normally uses another verb in the infinitive.

• Quiero visitar = I want to visit
• Quiero comer = I want to eat
• Quiero ir = I want to go

This is the same basic pattern as in English: want + to + verb.
In Spanish, it is simply querer + infinitive, with no separate word for to.

Pueblo usually means village or small town. It does not usually mean a large city.

In Spain, un pueblo often suggests:

• a smaller place
• less urban than una ciudad
• sometimes a more traditional or rural setting

So:

• pueblo = village / small town
• ciudad = city

Depending on context, pueblo can also mean people or nation, but in this sentence it clearly means a village/small town.

Because de + el contracts to del in Spanish.

• de + el = del
• So del noroeste literally means of/from the northwest

This contraction is required in normal Spanish.

Compare:

• el libro del profesor = the teacher’s book
• un pueblo del noroeste = a town in the northwest / from the northwest

One important exception: with feminine article la, there is no contraction.

• de la costa
• not dela

Del noroeste describes what kind of village it is: one from/in the northwest.

So un pueblo del noroeste means something like:

• a village in the northwest
• a village from the northwest region

In natural English, we often translate it with in rather than of, even though Spanish uses de.

In Spanish, compass directions like northeast, northwest, etc. are commonly written as single words:

• noreste = northeast
• noroeste = northwest
• sureste = southeast
• suroeste = southwest

So noroeste is the normal spelling.

Spanish often uses the definite article with time expressions, especially with seasons.

• el próximo otoño = next autumn
• literally, something like the next autumn

This is very natural in Spanish.

You will also often see articles with seasons in general:

• Me gusta el otoño. = I like autumn.
• En el otoño... / En otoño... = In autumn...

In this sentence, el próximo otoño is the normal way to say next autumn.

Adjectives in Spanish can come before or after the noun, but some are very commonly placed before it, especially in fixed time expressions.

• el próximo otoño = next autumn
• la próxima semana = next week
• el próximo año = next year

This position sounds natural and standard.

You may also hear el otoño próximo, which is grammatical, but el próximo otoño is usually the most common and neutral form.

Yes, but it depends on the structure of the sentence.

In your sentence:

• Quiero visitar un pueblo del noroeste el próximo otoño.

the phrase el próximo otoño works directly as a time expression, so no preposition is needed.

You could also say:

• Quiero visitar un pueblo del noroeste en el próximo otoño.

But this often sounds a bit heavier or less natural in everyday Spanish. The version without en is usually smoother here.

Compare:

• Voy a viajar el próximo otoño. = I’m going to travel next autumn.
• Viajo en otoño. = I travel in autumn.

Because Spanish does not need it in this structure.

English:

• I want to visit

Spanish:

• Quiero visitar

After verbs like querer, poder, deber, and necesitar, Spanish usually puts the next verb directly in the infinitive:

• Quiero aprender. = I want to learn.
• Puedo ayudar. = I can help.
• Debo estudiar. = I must study.

So the infinitive itself does the job.

Yes. They are part of the correct spelling and pronunciation.

• próximo has a written accent on ó
• otoño has ñ, which is a different letter from n

These marks matter:

• próximo tells you where the stress goes: PROK-si-mo
• ñ in otoño gives the ny sound, roughly like in canyon

So:

• otoño is correct
• otono is incorrect

Spanish word order is often flexible, but this order is very natural:

• Quiero visitar = verb phrase
• un pueblo del noroeste = what you want to visit
• el próximo otoño = when

This is a straightforward pattern: verb + object + time

You could move the time phrase for emphasis:

• El próximo otoño quiero visitar un pueblo del noroeste.

That is also correct, but the original sentence is very neutral and natural.

Yes. Both are correct, but they sound slightly different.

• Quiero visitar... = I want to visit...
• Me gustaría visitar... = I would like to visit...

Me gustaría sounds softer and a bit more polite or tentative.
Quiero is more direct and simple.

So:

• Quiero visitar un pueblo del noroeste el próximo otoño.
  direct, natural
• Me gustaría visitar un pueblo del noroeste el próximo otoño.
  a little softer

No. By itself, noroeste just means northwest. The sentence does not specify northwest of where.

Depending on context, it could mean:

• the northwest of Spain
• the northwest of another country
• a broader region

If you wanted to be specific, you could say:

• del noroeste de España = in/from the northwest of Spain

Without that extra information, the phrase stays general.
